This paper studies the current counternarcotics methods and the electronics technology used by the United States and Colombian governments to combat narcoterrorism in the Andean region. The efficiency and efficacy of these methods with the use of electronics technology are analyzed to determine if they are
successful. The current counternarcotics...
To observe the effects of oviposition as related to time of insemination
on fertility, four trials were conducted in which individually
caged White Leghorn hens were artificially inseminated with 0.05 cc
of undiluted mixed semen obtained from 4 to 5 cockerels. These inseminations
were made at 9:45 a.m. , 10:00...
Hens were artificially inseminated at 8:00 a.m., 4:00 p.m.
and 11:50 p.m. Fertility was found to be significantly lower after
8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations
for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations.
Slightly higher fertility...
In recent years the “working landscape” concept has risen to prominence in popular, academic, and policy discourse surrounding conservation of both natural and cultural values in inhabited landscapes. Despite its implied reconciliation of commodity production and environmental protection, this concept remains contested terrain, masking tensions over land use practices and...
In 1997, the Eskimo Walrus Commission (EWC) and the U.S. Fish and Wildlife Service (USFWS) established a formal cooperative agreement for the conservation and management of Pacific walrus (Odobenus rosmarus divergens). This arrangement facilitates the transfer of funds from Section 119 of the Marine Mammal Protection Act via the USFWS...
The subject of Traditional Ecological Knowledge (TEK) is currently attracting interest from many quarters,
including biologists and philosophers as well as the more traditional mix of anthropologists and other social scientists. Given
rapid contemporary rates of change, as well as the novel species and environments being created by six billion...
Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
The fundamental physics of turbulence in plasma is not well understood. Recent studies of the plasma deflagration accelerator in the High Temperature Gasdynamics Lab at Stanford University have demonstrated the presence of small scale instabilities that limit the lifetime of the jet/Z pinch and are not reproduced by coaxial plasma...
There is a pressing need for Micro Air Vehicles (MAV) that are light, powerful, and efficient to perform military reconnaissance missions and search and rescue operations. These MAVs have length scales on the order of 10 cm, where traditional steady flight wing designs perform poorly. An alternative flight mechanism is...
Sediments of the central Chile margin record changes in ocean circulation and
continental erosion associated with large–scale climate change. Here Antarctic–
influenced Southern Ocean currents flow equatorward, forming a link between the high–
and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important
conduit that ventilates South...
